### get
|
||||
|
||||
Retrieve a set of properties indicated by the given selectors from an object.
|
||||
|
||||
Use `Array.map()` for each selector, `String.replace()` to replace square brackets with dots, `String.split('.')` to split each selector, `Array.filter()` to remove empty values and `Array.reduce()` to get the value indicated by it.
|
||||
|
||||
```js
|
||||
const get = (from, ...selectors) =>
|
||||
[...selectors].map(s =>
|
||||
s
|
||||
.replace(/\[([^\[\]]*)\]/g, '.$1.')
|

||||
